Changes to tongue, hands or feet may be a sign of Covid-19 - study

Changes to a person’s tongue, hands or the soles of their feet could provide an early indication that they are infected with Covid-19, Spanish researchers say.


In a study presented on Tuesday, the researchers said that among 666 patients with Covid-19 at Madrid’s IFEMA field hospital set up during the first wave of the pandemic, one in four patients said they had noticed changes to their tongue. Four out of 10 also noticed unusual signs on the palms of their hands or soles of their feet.


The study was carried out in April by healthcare professionals from Madrid’s La Paz hospital and primary care services. The findings were published in the British Journal of Dermatology in the form of a “research letter” in September.


Some patients said they experienced swelling of their tongues and the appearance of patches – something which has now been dubbed ‘Covid tongue’. This was also associated with a loss of taste.


Another symptom was a burning sensation and redness on the palms or soles of the feet, which in some cases was also followed by the appearance of small blemishes.


“Almost half of patients with mild‐to‐moderate Covid‐19 admitted in a field‐hospital during a two‐week period showed mucocutaneous findings,” the researchers said.


“The oral cavity was frequently involved and deserves specific examination under appropriate circumstances to avoid contagion risk.”
